The 430-1002114 cylinder block is cast from a specially formulated pearlitic gray iron (GGG‑30 equivalent) that offers excellent strength, damping capacity, and machinability. The casting process includes precision‑placed core passages for coolant and oil galleries, ensuring optimal temperature control and lubrication. The cylinder bores are induction‑hardened to a depth of 1.5‑2.0 mm, achieving a surface hardness of 45‑50 HRC, which resists wear from piston ring friction and extends engine life.
Each 430-1002114 block undergoes rigorous dimensional inspection, including main bearing bore alignment, cylinder bore roundness, and deck flatness. The block is pressure‑tested to 5 bar to verify coolant and oil passage integrity. All critical bolt holes are tapped to exact depths and inspected for thread quality. This meticulous attention to detail guarantees that the block provides a perfect foundation for the crankshaft, connecting rods, and cylinder head, ensuring long‑term reliability under peak loads.

The 430-1002114 cylinder block is a direct OEM replacement for the engine blocks used in Howo heavy‑duty trucks, including the widely used WD615 series (Euro‑2 to Euro‑5), the MC11 and MC13 engines in T7H and C7H models, as well as the D10 engines. It houses the crankshaft, connecting rods, pistons, and camshaft, and provides the rigid structure needed to withstand peak combustion pressures exceeding 200 bar.
In chassis applications, the cylinder block’s integrity is paramount for engine longevity. A cracked or warped block can lead to coolant leaks, oil contamination, and catastrophic failure. The genuine 430-1002114 block ensures that all mounting points for ancillaries (alternator, starter, etc.) are precisely located, simplifying assembly and guaranteeing a perfect fit.
When replacing a cylinder block, always use new core plugs and ensure all oil passages are thoroughly cleaned. The block should be checked for flatness before installing the cylinder head.
Correct installation of the 430-1002114 cylinder block is critical to ensure engine reliability and long service life. Follow these steps:
Clean the block thoroughly, removing all shipping preservative. Install new core plugs and oil gallery plugs. Check all threaded holes for damage and clean them with a tap if necessary.
Install main bearings and crankshaft, following torque specifications and sequence. Measure crankshaft end‑play and main bearing clearance. Install pistons and connecting rods, ensuring proper orientation.
After assembling the short block, check deck flatness. Install the cylinder head with a new gasket. Prime the oil system before initial start‑up.
A cracked or worn cylinder block can cause coolant loss, oil contamination, and engine failure. Common signs that replacement is needed include:
If any of these symptoms are observed, immediate replacement with a genuine 430-1002114 cylinder block is recommended. Attempting to repair a cracked block is rarely cost‑effective and may compromise engine reliability.
High‑grade cast iron and rigid design withstand extreme combustion pressures and thermal loads, ensuring long‑term durability.
Induction‑hardened bores and precision‑machined bearing saddles reduce wear, extending overhaul intervals and lowering operating costs.
Manufactured to original specifications, the block ensures correct alignment of all rotating and reciprocating components, guaranteeing optimal performance.
To maximize the service life of your 430-1002114 cylinder block, follow these best practices:
By adhering to these guidelines, you ensure that the 430-1002114 block performs optimally throughout its intended service interval.
Aftermarket cylinder blocks are often made from lower‑grade iron with inferior casting quality, leading to porosity, misaligned bores, and premature failure. The genuine 430-1002114 is manufactured to the exact specifications of the original equipment, using premium pearlitic gray iron and state‑of‑the‑art casting techniques. Each block is inspected for dimensional accuracy, material integrity, and pressure tightness, guaranteeing that it will perform exactly as the original part.
By choosing authentic SINOTRUK HOWO parts, you protect your investment and ensure your truck maintains its power, reliability, and resale value. The Sinotruk howo parts catalog includes a full range of engine and chassis components engineered for maximum durability. For fleet managers and owner‑operators who demand the best, the genuine 430-1002114 is the only responsible choice.
The 430-1002114 cylinder block is used across a wide range of Howo models: T7H, A7, and classic Howo‑7 series equipped with WD615, MC11, MC13, and D10 engines. Always verify the engine series and block height using the service manual; different power ratings may have minor variations in casting.
Each 430-1002114 is individually wrapped in rust‑inhibiting oil and secured in a heavy‑duty wooden crate to prevent damage during shipping. The package includes the block only; main bearings, core plugs, and other components must be ordered separately.
Production of the 430-1002114 takes place in IATF 16949 certified foundries, using precision sand casting and CNC machining with in‑process gauging. Statistical process control ensures that dimensional variations are kept to a minimum, far exceeding the requirements of the original design. Every batch is accompanied by a material certificate and pressure test report, guaranteeing that the blocks delivered are identical to those fitted on new Howo trucks at the factory.
